    import _LibreDWG
ModuleNotFoundError: No module named '_LibreDWG'

I'm having the same problem on my windows machine. Is it possible to import this as an library without building it? In other words, can I use the pre-built download package for windows and some how configure it to run in python?

The prebuilt mingw packages do include the python bindings,
but you need to have the very same python version as mingw.
And you need to install them by yourself into your python site-packages

See build-aux\msys2.bat and build-aux\appveyor-deploy.bat
=> lib/python3.10/site-packages/_LibreDWG-0.dll

Thanks I'll try that!

One workaround that works for me since my goal is to extract text from drawings.
Either convert DWG->DXF and search the DXF-file for text (a DXF file is just a glorified .txt-file) or search directly in the file with regex.
I couldn't use the executables directly due to my companys IT-security but calling them from python worked. See example below:

import subprocess
import glob

paths = glob.glob(r"C:\path\to\dwgfiles\*.dwg")
for path in paths:
    subprocess.call(
        # Case 1
        # Find dates with regex in format NNN-NN-NN
        # [r"C:\projekt\libredwg\dwggrep.exe", r"\d{4}-\d{2}-\d{2}", path]
        
        # Case 2
        # Convert to DXF
        [r"C:\projekt\libredwg\dwg2dxf.exe", "-v0", "-y", path]  
    )

I'm having the same problem on my windows machine today, maybe python on windows perfer to _LibreDWG.pyd than _LibreDWG.dll
